A pennyweight was a unit of mass that was equal in weight to 20 grains, one twentieth of an ounce and one 240th of a Troy pound. The abbreviation for a pennyweight is ‘dwt’ (denarius weight). These measures and weights were typically used for weighing gold and other precious metals. Group of eleven weights and measures including seven rectangular pennyweights with clipped corners and marked 10 DWTS, 6 DWTS, 5 DWTS, 4 DWTS, 3 DWTS, 2 DWTS respectively, two gram weights; 5 grams and 4 grams with top right pressed corner and two cup troy weights marked 4oz TROY and ½.284.1 10 DWTS 284.2 6 DWTS 284.3 5 DWTS 284.4 4 DWTS 284.5 3 DWTS 284.6 2 DWTS 284.7 1 DWTS 284.8 5 GRAMS 284.9 4 GRAMS 284.10 4 oz TROY 284.11 ½ city of greater bendigo commerce, making a nation exhibition, city of greater bendigo mining

The Pacific Marine company was based in Seattle on the west coast of America and manufactured its first satisfactory portable fire pump 1925. These early Type N pumps were replaced in 1933 by the more familiar Type Y pumps. The updated pumps proved popular with the US Forest Service, and a large number were purchased by the Forests Commission as part of the equipment upgrade program in the wake of the 1939 bushfires. The Pacific Marine had a 9.8 Hp, two-cylinder, two-stroke petrol motor running with a high oil mix ratio of 16:1, so it blew vast clouds of blue smoke as the motor screamed at 4500 rpm. Part of its unique design was the water-cooled engine and muffler. But if the flow of water was interrupted the engine would quickly overheat and seize, so it needed constant monitoring and attention. Water was driven through a pair of bronze impeller gears which also needed a constant flow of water otherwise they would also self-destruct. When running properly, a Pacific Marine could pump 63 US gallons per minute, or about enough to fill a 200-litre drum. But its main feature was its high pressure of up to 225 psi. Pacific Marine pumps were often mounted on top of departmental fire tankers and used to spray water into the tops of burning trees. Compared to other pumps of the era it was light weight at only 70 pounds and was often mounted on a wooden stretcher frame. But they were cantankerous things to start with the rope pull and many exasperated novices came away with skinned knuckles. Modern Honda motors, which were more reliable and smoother running, replaced the Pacific Marines as the pump of choice for forest firefighters in the 1980s.High pressure Pacific marine Pumpforests commission victoria (fcv), bushfire, fire pump

Troy weight is a system of units of mass from an unknown origin. While the name Troi is believed to have come from Troyes in the north east of France the system used primarily in the precious metals industry and adopted in Australia originated in 15th century England. Troy weight units are the 'grain' and 'pennyweight' (24 grains), the troy ounce (20 pennyweights), and the troy pound (12 troy ounces). One troy ounce equals 31.1034768 grams. The troy ounce and grain were also part of the apothecaries' system and was long used in medicine, but has now been largely replaced by the metric system (milligrams). When the Weights and Measures Act was passed in Victoria in 1862 local inspectors were established throughout the colony to ensure accuracy particularly in the weighing of gold. By the 1870's each local council had a set of standards that were used to test the scales, weights and measures of local merchants and businesses. This set would have been de commissioned some time after 1947 and was offered back to the Borough of Eaglehawk in 1989. Hinged, lockable wooden box with brass handle, hinges, latches and lock. Remnant wax on front face of box above and below lock. Interior of box is lined with purple velvet which is worn in several places.

There were at least three 1880s vessels named Lady Loch, all built in Victoria; a river launch (ca 1884 to ca 1916, originally named Lady of the Lake), a steamer ferry (1884 to 1920s), and a government lighthouse tender steamer HMV Lady Loch (1886 to 1962). The spring balance scale was part of the equipment on the HMV Lady Loch. The scale was made by the renowned company Salter Weighing Machines in the United Kingdom, to Silvester's patent design. Salter Weighing Machines, Britain, began making spring scales in the 1820s. In 1908 Salter opened up an Australian branch named Salter Scales Pty. Ltd. The scale is marked HMV SS Lady Loch. It would be suspended by its top ring, a basket or other container is hung from the hook, and the items inside the basket are then pulled downwards on the hook, which stretches the springs inside the works. The pulling action moves a rack and gears a calculated distance and the gears turn the pointer on the dial to indicate the weight of the goods. This scale measures up to 200 pounds capacity. The HMV SS Lady Loch was an iron steamship built in Footscray, Melbourne, by Campbell, Sloss and McCain in 1886 for the colonial Victorian government’s Department of Trade and Customs. It was armed with a 6-inch gun and two 1-inch Nordenfelt guns. The Sydney Morning Herald of 27th January 1888 describes the vessel in detail. It even comments on the interior of the Saloon “The wood work … is on a very elaborate scale and is exceedingly neat …”. The HMV Lady Loch performed Customs duties and serviced the lighthouses along the coast. The scale could have measured goods for the Customs Tax, or for measuring out supplies for the lighthouse keepers. The vessel was named after Lady Elizabeth Loch, wife of Sir Henry Loch, Governor of Victoria from 1884 to 1889. In 1932 Lady Loch was converted to a hulk and used in Brisbane, and finally scuttled in 1962 at Moreton Bay, Queensland.The scale has importance due to its connection to the 1886 HMV Lady Loch, a vessel of great significance to Melbourne’s shipbuilding industry. It was the largest auxiliary vessel in the Victorian Colonial Government’s fleet and the first prominent vessel launched by Melbourne’s shipbuilding industry. The scale is also important for its connection with the colonial navy's Custom's work, as the scale was available to weigh goods that could attract taxes and deal out goods for distribution to lighthouse keepers. The HMV Lady Loch was also important part of Victoria's maritime history for its communication and support of the lighthouse keeper's along the coast of Victoria.Scale; Salter's spring balance mechanical hanging scale, brass and iron. Equally spaced marks around the circular dial have values from 0 to 200 in increments of 10, each increment is also divided into 10. An iron ring is attached to a fitted loop on the top of the scale, and an iron hook is attached to the fitted loop onthe bottom of the scale. A moving pointer attached to the centre of the dial has a calibration screw joined to its base. Four screws fix the brass face to the works at the back. There are stamped and embossed inscriptions. Made by Salter in Britain, to Silvester's Patent design. The scale was once equipment carried abourd the steamship HMV SS Lady Loch.

The lead line or hand lead is a simple navigational instrument used as a depth finder to measure the depth of water under the ship’s keel and to take samples of the sea bed. The long line may be marked at regular intervals with tags of different coloured and textured fabric, such as rope, leather and cloth. Each tag was a code to represent a certain depth. The leadsman’s eyes and hands could distinguish the depth easily as he drew in the lead line, day or night and in poor weather conditions. A standard set of codes for the tags was used so that the depth of the sea could be easily and quickly read. The measurement used was a Fathom, which equals 1.83 metres. The codes were: - 2 fathoms = 2 strips of leather 3 fathoms = 3 strips of leather 5 fathoms = white duck fabric 7 fathoms = red bunting fabric 10 fathoms = leather with a hole 13 fathoms = blue serge fabric 15 fathoms = white duck fabric 17 fathoms = red bunting 20 fathoms = 2 knots The lead weight could be between 7 -14 pounds (3.5 – 6.5kg) and the rope would be approximately 25 fathoms (45m). The hollowed-out end of the weight would hold a stick substance such as tallow or wax, which would pick up samples from the sea bed which would show whether the vessel was close to, or far away from, the shore. The leadsman would stand at the front of the vessel and cast the lead line into the sea. When it hit bottom he would note the tag marker nearest the surface of the water and call out his finding. Then he would haul it up again and examine the kind of matter that adhered to the end of the weight, whether it be sand, mud, gravel, or the colour of it. This information would be given to the ship’s helmsman or navigator and would help indicate the proximity to the land.This handheld lead is an example of early marine navigational equipment used by sailors to travel the seas to measure the depth of the water and sample the nature of the seabed. It helps to understand the history and progress made from the very basic to the sophisticated technology of today.Lead line, sounding line or depth finder. The long length of rope has a heavy lead weight attached to the end. Coloured fabric tags are tied onto the rope at regular intervals, representing different depths. The concave base of weight holds sticky substances such as tallow or beeswax, providing an adhesive surface to collect samples of sea bed like sand, shells or pebbles. flagstaff hill, warrnambool, shipwrecked coast, flagstaff hill maritime museum, maritime museum, shipwreck coast, flagstaff hill maritime village, lead line, depth finder, hand lead, sounding lin, leadsmane, navigation instrument, leadline, hand lead line
